Abstract

Balance deterioration is a major risk factor for falling, particularly among the elderly. Early detection of emerging balance problems can allow behavioral and medical interventions to reduce the impact and severity of balance-related incidents. The iBalance technology presents a small, mobile platform that integrates hardware and software engineering for balance monitoring at a low cost for use in the home, physical therapy office, or other point of care setting. The hardware solution has the form factor of a bathroom scale and takes the standard approach of a force plate with four load cells arranged in the corners beneath the platform. The load cells output 12-bit data to a computing device running the accompanying software. There is less scientific consensus about the most effective software solution for performing analysis on balance data. A survey of the literature reveals 16 commonly used metrics of balance derived from force plate data. Using principal component analysis, we identify three underlying clusters of metrics from which a representative metric for each cluster may be chosen to construct an exogenous balance score. Finally, we have developed a graphical user interface for the iBalance that allows researchers to collect raw and/or processed data and view analytic visualizations of the data, with ease of extensibility for further research and analysis.
